+## what

+- Use bullet points to be concise and to the point.
+-->
+- add engine input for valkey support
+
+## why
+
+<!--
+- Provide the justifications for the changes (e.g. business case).
+- Describe why these changes were made (e.g. why do these commits fix the problem?)
+- Use bullet points to be concise and to the point.
+-->
+- Valkey is far cheaper than redis
+
+<details><summary>Notes</summary>
+
+- Design options
+    1. Add a new key to `local.cluster_attributes` and add a variable to the component, default it to `redis`, and pass as an argument to the module as-is
+        - We could shy away from the pattern to using `engine = var.engine` in the `local`.
+    1. Allow `var.redis_clusters` to supply `engine` with a default for `redis` and pass to module as-is
+    1. Same as option 2 but allow `local.cluster_attributes` to overwrite it
+        - This might be best of both worlds however no other argument does this so it would be breaking the pattern
+- Went with option 2 so the argument isn't a new requirement for everyone and it doesn't break consistency

+## references

+- Link to any supporting github issues or helpful documentation to add some context (e.g. stackoverflow).
